Naniwa NA-0040 New Arata Professional Medium Whetstone #400 8.3 x 2.8 x 0.6 inches (210 x 70 x 15 mm) Green

Very nice sharpening stone. One of the best I’ve used. I mostly use Shapton Pro (1k and 5k). Compared to those, I would say that this is more fine-grained than the grit would suggest, maybe more like a 3k. This is not a fast sharpening stone, so you’ll need something courser to start on a dull knife, but this stone has good feed-back and leaves a very nice edge. I’m fairly decent with sharpening stones, but also pretty lazy so I tend to use no more than 2 stones on a given knife. For western knives, this is too fine-grained for me to bother. My Japanese knives tend to be kept pretty sharp, so I can usually start on this, and sometimes go to a 5k afterwards, but going from this stone to a leather strop can leave an extremely good edge. The plastic case is extremely flimsy and broke in shipping. Not a big deal but they are handy to have and wish the case was a bit better.

Pedra sensacional, muito gostosa de usar, proporciona um excelente feedback, aveludada, sua ação na remoção de material é rápida e fácil manutenção, não retém muitas partículas na superfície da pedra.

The plastic case to protect the stone was broken and there’s a small chip in the stone but all in all it is good as what you expected from the brand! Thank you

La piedra son buenísimas, pero el paquete sufrió daños y la caja de plástico llegó quebrada, afortunadamente las piedras llegaron intactas

Excelente piedra 100 % recomendable
